We introduce an approximation for the pair distribution function of the inhomogeneous hard sphere fluid. Our
approximation makes use of our recently published averaged pair distribution function at contact, which has
b ...

We develop a classical density functional for water which combines the White Bear fundamental-measure theory (FMT) functional for the hard sphere fluid with attractive interactions based on the statistical associating fl ...

Several studies in recent years have demonstrated that upper-division students struggle with partial derivatives
and the complicated chain rules ubiquitous in thermodynamics. We asked several experts (primarily faculty ...

We describe an upper-division experiment in thermal physics where students measure the tension
of a rubber band as a function of temperature and length, and use a Maxwell relation to find the
change in internal energy ...

We present a modification to our recently published statistical associating fluid theory-based classical
density functional theory for water. We have recently developed and tested a functional for the
averaged radial d ...

We introduce a series of activities to help students understand the partial derivatives that arise in thermodynamics. Students construct thought experiments that would allow them to measure given partial derivatives. The ...

Several studies in recent years have demonstrated that upper-division students struggle with the
mathematics of thermodynamics. This paper presents a task analysis based on several expert attempts
to solve a challengin ...

We investigate the value of the correlation function of an inhomogeneous hard-sphere fluid at contact. This
quantity plays a critical role in statistical associating fluid theory, which is the basis of a number of recen ...
